SHAPER- FOB PRINTING PLATES 03 THE LIKE.

Application filed Apri1 3, .1922. Serial No. 549,246.

To all 'wlzom it may concern.-

Be it known that I, CLAUDE L. Posr, a citizen of the United States, residing at Chicago, in the county of Cook and Stateof Illinois, have invented certain new and useful Improvements in a Shaper for Printing Plates or the like, of which the following is a description.

My invention relates to improvements in a shaper or former for printing plates or the like, and more especially to means for shaping or setting an electrotype, printplate, etching plate, or the like so that its shape will conform to the shape of the printing roll or the like upon which said plate is to be mounted for its printlng operation. The invention has among its other objects the production of device of the kind described that is simple, convenient, compact, durable, reliable, eflicient and satisfactory for use wherever found applica ble. Many oth r objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end, my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts,

standards, uprights or frame members 1,-

each having a bored boss 2 thereonto rotatably receive the ends 4 of a forming or shaping roll 3. A set screw 5, or other suitable or equivalent means, is threaded into one of the bosses 2, as shown in the drawings, to engage one of the ends 4 of the roll 3 and hold it againstrotation when ever desired. One or more brace rods 6 and '7 may be secured between the stand ards 1 to hold them in place and prevent any accidental displacement of the parts.

A. plate or rod 8 is adapted to be arranged longitudinally of the roll 3 and to be ad- 1 is a front elevation of my dejustably clamped on said roll by means of a series of spaced screws 9, each preferably having a washer 1O betweenits head and the plate. Any suitable printing plate, electrotype or the like may be shaped about the roll 3 and in the embodiment shown, there is represented a printing plate 11,having any sort of imprint design v12 thereon.- The plate is adapted to be arranged on said 55 roll with one edge 13 clamped between the rod 8 and the roll, as shown more clearlyv 1 in the drawings. It will be noted that the edge of the rod 8 forms a straightedge whereby the printing-plate may be aligned as desired. c

Any suitable means forpressi-ng the plate about the roll may be employed, but I have found it satisfactory to use a hand tool having a handle portion 1a and a head portion 15 at one end thereof to cooperate with the roll to bend, set or shape the printing plate 11 thereabout. The head portion 15 of the tool forms .a T with the handle portion 14:, and the end of the head portion is tapered or beveled, asat 16, so as to form I a very narrow edge or face to bear upon or engage the printing plate. without danger of marring the raised printing design thereof. Where the printing plate 11 has any sort of imprint thereon, it is possible to have the striking face of the tool engage said plate between the lines of the imprint,

as the tool has a very narrow face. In some cases, for example where a half tone plate '90 is to be formed a block of wood or the equivalent may be placed on the face while forming.

An aperture 17 may be provided at any suitable point in the handle for the purpose of hanging up said tool when desired, and for the additional purpose of engaging the pins with which the set screws 5 and 9 are provided to tighten or releasesaid screws. In operation, one edge of the plate is adjustably clamped between the plate 8 and roll 3, and with a mallet or. any other suitable tool, the face 16 of the T-head tool is caused to be pressed upon the plate 11 to shape it about said roll. In order that the portion of the plate 11 that is to bentabout the roll may always be at the most con- ,venient or advantageous portion of the roll, the set screw 5 may be released so that the roll may be partially rotated to bring the plate to the desired position to be worked upon, until it is desired to release it again to more the roll farther. It will be apparent that the from side of the device, Which is toward the free edge of the plate 11, is clear of obstruction, as the brace rods 6 and 7 are placed upon the rear portion of the standards. This makes it very easy to align the plate and perform the bending operation Withouthindrance. When a plate is formed or set upon the shaping roll 3, it will conform exactly to periphery of said roll and as said periphery is exactly like that of the printing roll or other holding means in the printing press upon which the plate 11 is to be secured'l or printing, the under surface of the plate Will conform precisely to the body contour of said lastmentioned means.

Having thus described my invention, it is obvious that Various immaterial modifications may be made in the samewithout departing from the spirit of my invention;

hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned.

V hat I claim as new and by Letters Patent is:

1. 1n a device of the kind described and in combination, a roll, means for rotatably mounting said roll, means for adjustably locking said roll at any point of its rotation, and means for shaping a printing plate about said roll to conform to the peripheral surface of said roll.

2. In a device 01" the kind described and in desireto secure combination, a frame, a roll journaled therein, means for locking said roll at any point of its rotation, a bar arranged longitudinally of said roll, adjusting screws .i or clamping the edge of a printing piate between said bar andIroll and means for pressino' said plate on said roll so that it may be shaped to conform to the peripheral surface of said roll,

3. In a device of the kind dessrihed and in combination, a shaping roll having a peripheral surface conforming to that oi the plate-holding roll of a printing mechanism, a frame for rotatably carrying said roll, neans for locking said roll in said frame at any point of its rotation, and means for holding a printing plate on said roll for shaping it thereabout.

4:. In a device of the kind described and in combination, a shaping rollhaving a peripheral surface conforming to that of the plato-holding roll of a printing mechanism, a frame having bored bosses for rotatably carrying said roll, means for locking said roll in said bosses of said frame at any point of rotation, and means for adjustably clamping a printing plate on said roll along one edge for shaping said plate about said roll.

In testimony whereof, I have hereunto signed my name in the presence of two sub scribing Witnesses.
